RESUMEN
OBJECTIVES: This study aimed to determine the normal vasculature indices of the endometrium and to correlate them with those in various physiological states. METHODS: Women undergoing ultrasound at the Feto-Maternal Center, Qatar in 2020-2021 as part of their gynecologic evaluation were enrolled into the study. They were divided into those with normal menses and no additional pathology, those following spontaneous miscarriage, postpartum and menopausal. Three-dimensional (3D) evaluation of the endometrial vasculature was done and the parameters quantified included vascularization index (VI), flow index (FI), vascularization flow index (VFI), endometrial thickness, endometrial volume and uterine volume. JASP, an open-source statistical analysis software, was used for analysis and an independent t-test to compare the vascularity indices. A multivariate regression analysis was also done to look at the factors affecting the endometrial vascular indices within the luteal phase. RESULTS: A total of 461 women were studied: 122 in the follicular phase, 199 in the luteal phase, 90 after a spontaneous miscarriage, 29 postpartum, and 16 menopausal. The vascularity indices were highest after miscarriage and lowest postnatally. There were no significant effects of age, gravida, para, or abortions on VI and VFI. However, there was a significant positive effect of age on FI (P = 0.019) There was a significant increase in endometrial volume and thickness in the luteal phase as compared to follicular phase (P < 0.01), but there was no difference in the vascularity indices. The uterine and endometrial volume in the postnatal group were nearly double that of the luteal group (P value <0.01 and 0.014, respectively). There was a significant decrease in flow index in the postnatal group compared to the luteal group (P < 0.01), suggesting low flow intensity in the postnatal group. CONCLUSIONS: Endometrial vascular indices measured using 3D Doppler can be used to determine normal vascular indices and vary with physiological states such as after miscarriages, postnatally and in the menopausal states.

INTRODUCTION: Early prediction of pregnancies destined to miscarry will allow couples to prepare for this common but often unexpected eventuality, and clinicians to allocate finite resources. We aimed to develop a prediction model combining clinical, demographic, and sonographic data as a clinical tool to aid counselling about first trimester pregnancy outcome. MATERIAL AND METHODS: This is a prospective, observational cohort study conducted at Queen Charlotte's and Chelsea Hospital, UK from March 2014 to May 2019. Women with confirmed intrauterine pregnancies between 5 weeks and their dating scan (11-14 weeks) were recruited. Participants attended serial ultrasound scans in the first trimester and at each visit recorded symptoms of vaginal bleeding, pelvic pain, nausea and vomiting using validated scoring tools. Pregnancies were followed up until the dating scan (11-14 weeks). Univariate and multivariate analyses were performed to predict first trimester viability. A model was developed with multivariable logistic regression, variables limited by feature selection, and bootstrapping with multiple imputation was used for internal validation. RESULTS: 1403 women were recruited and after exclusions, data were available for 1105. 160 women (14.5 %) experienced first trimester miscarriage and 945 women (85.5 %) had viable pregnancies at 11-14 weeks' gestation. The average gestational age at the initial visit (calculated from the menstrual dates) was 7 + 1 weeks (+/-12.2 days). A multivariable logistic regression model was developed to predict first trimester viability and included the variables: mean gestational sac diameter, presence of fetal heart pulsations, difference in gestational age from last menstrual period and from mean sac diameter on ultrasonography, current folic acid usage and maternal age. The model demonstrated good performance (optimism-corrected area under curve (AUC) 0.84, 95 % CI 0.81-0.87; optimism-corrected calibration slope 0.969). CONCLUSION: We have developed and internally validated a model to predict first trimester viability with good accuracy prior to the 11-14 week dating scan, which now needs to be externally validated prior to clinical use.

INTRODUCTION: This retrospective single centre study considers the predictive value of specific ultrasound features of sub-chorionic haemorrhage (SCH) as potential indicators of adverse pregnancy outcome. METHODS: Ultrasound reports and images were reviewed for 160 participants presenting to an early pregnancy assessment unit from January 2018 to January 2019. Participants were selected based upon the presence of SCH within the first trimester. The outcome of each pregnancy and the features of SCH, including the size, location and echogenicity were recorded and multinominal logistic regression was used to establish predictive value. RESULTS: The majority of participants were asymptomatic and delivered healthy babies. 24% miscarried prior to delivery or had stillborn babies; the features of bleed within this group revealed an increased prevalence of adverse outcome in the presence of moderate sized haemorrhage (p = 0.02). 61% of miscarried pregnancies presented with "wrapping" SCH, in which haemorrhage encased the gestation sac, suggesting wrapping posed a probable risk (p = 0.01). 71% of miscarriages occurred within 5 + 0-10 + 0 weeks gestation. Persistent SCH was of greater incidence within those participants with adverse outcome (57%). There was no association between fetal abnormality and miscarriage. Jaundice babies and premature delivery occurred more frequently (p = 0.001) and may be a secondary finding following SCH. CONCLUSION: There was a strong correlation between presence of SCH in early pregnancy and rate of miscarriage. Specific ultrasound features of SCH, most notably a wrapping location with moderate size, may be indicative of increased risk of miscarriage or post-natal complications. Jaundice and premature births may have an association with placental compromise.

Our primary objective is to verify or refute a 2013 study by Connolly et al. which showed that in early pregnancy, a gestational sac was visualized 99% of the time on transvaginal ultrasound when the HCG level reached 3510 mIU/mL. Our secondary objective was to make clinical correlations by assessing the relationship between human chorionic gonadotropin (HCG) level in early pregnancy when a gestational sac is not seen and pregnancy outcomes of live birth, spontaneous abortion, and ectopic pregnancy. This retrospective study includes 144 pregnancies with an outcome of live birth, 87 pregnancies with an outcome of spontaneous abortion, and 59 ectopic pregnancies. Logistic regression is used to determine the probability of visualizing a gestational sac and/or yolk sac based on the HCG level. A gestational sac is predicted to be visualized 50% of the time at an HCG level of 979 mIU/mL, 90% at 2421 mIU/mL, and 99% of the time at 3994 mIU/mL. A yolk sac was predicted to be visualized 50% of the time at an HCG level of 4626 mIU/mL, 90% at 12,892 mIU/mL, and 99% at 39,454 mIU/mL. A total of 90% of ectopic pregnancies presented with an HCG level below 3994 mIU/mL. These results are in agreement with the study by Connolly et al. Since most early ectopic pregnancies had an HCG value below the discriminatory level for gestational sac visualization, other methods for the evaluation of pregnancy of unknown location such as repeat HCG values are clinically important.

Autopsy investigations provide valuable information regarding fetal death that can assist in the parental bereavement process, and influence future pregnancies, but conventional autopsy is often declined by parents because of its invasive approach. This has led to the development of less-invasive autopsy investigations based on imaging technology to provide a more accessible and acceptable choice for parents when investigating their loss. Whilst the development and use of more conventional clinical imaging techniques (radiographs, CT, MRI, US) are well described in the literature for fetuses over 20 weeks of gestational age, these investigations have limited diagnostic accuracy in imaging smaller fetuses. Techniques such as ultra-high-field MRI (>3T) and micro-focus computed tomography have been shown to have higher diagnostic accuracy whilst still being acceptable to parents. By further developing and increasing the availability of these more innovative imaging techniques, parents will be provided with a greater choice of acceptable options to investigate their loss, which may in turn increase their uptake. We provide a narrative review focussing on the development of high-resolution, non-invasive imaging techniques to evaluate early gestational pregnancy loss.

OBJECTIVE: Ultrasonographic features of the endometrium are often assessed when deciding the necessity of surgical intervention following early medical abortion. Knowledge is therefore needed on the ultrasonographic appearance of the endometrium following successful medical abortion in order to avoid unnecessary surgical interventions. We aimed to assess endometrial thickness and echogenicity at multiple time points following successful early medical abortion. STUDY DESIGN: We conducted a retrospective study in the largest office-based abortion providing clinic in Denmark. Using archived ultrasonographic images, we assessed endometrial thickness and echogenicity following all early medical abortions that did not need surgical intervention or repeated medication for completion during the years 2014-2017. RESULTS: Ultrasonographic endometrial features were assessed 1854 times following 1074 early medical abortions. Median endometrial thickness in the 1st week from induction was 13 milimeters (mm; lower-upper quartile 11-17 mm). For the 2nd, 3rd, 4th, and >4th week, the median endometrial thickness was found to be 11 mm (9-15 mm), 11 mm (8-14 mm), 12 mm (9-16 mm), and 11 mm (8-14 mm), respectively. Of the ultrasonographic examinations performed in the 1st week from medical induction, 24.7 % showed a heterogenous endometrium. For 2nd, 3rd, 4th, >4th week, the frequency of heterogeneity was 23.9 %, 16.3 %, 21.3 %, 18.9 %, respectively. A total of 151 abortions (14.1 %) were each examined three times, median time of examination being day 7, 15, and 26 following induction. Among these abortions, the three most common patterns of change in endometrial thickness were "decreasing" (37.7 %), "increasing-decreasing" (23.2 %), and "decreasing-increasing" (21.9 %). Further, 49.7 % of the 151 abortions showed a homogenous endometrium at all three examinations, 17.2 % showed a heterogenous endometrium at first examination and a homogenous endometrium the following two examinations, and 9.9 % showed a heterogenous endometrium at the first two examinations followed by a homogenous endometrium. CONCLUSION: In early medical abortions completed without secondary intervention, endometrial thickness and echogenicity varied clinically significantly for weeks following the medical induction. Every possible pattern of change in endometrial thickness and echogenicity was observed.

OBJECTIVE: To find the relationship between the volume ratio of subchorionic hematoma (SCH) to gestation sac measured by three-dimensional ultrasound and pregnancy outcome of patients with threatened abortion. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: The Second Affiliated Hospital of Soochow University, Suzhou, China, from January 2016 to December 2020. METHODOLOGY: Medical data of patients, who were diagnosed with threatened abortion (persistent or intermittent vaginal bleeding) were collected. All included patients underwent ultrasonography for SCH at gestation age of 6-8 weeks. According to the patients' evaluation, they were classified into a case group combined with threatened abortion and SCH (n=145), and a control group with threatened abortion (n=76). The clinical data and three-dimensional ultrasound parameters of the two groups were compared to find the relationship between the volume ratio of SCH to gestation sac and pregnancy outcome. RESULTS: In the case group, the hospital stay was longer, the abdominal pain, its duration ≥7 days, and adverse pregnancy outcomes were higher than in the control group (p<0.05). Patients with moderate and severe area ratio and volume ratio of SCH to gestation sac were significantly related to higher abortion and stillbirth rates than patients with mild ratio (p<0.05). The area under the curve, sensitivity and specificity of the volume ratio of SCH to gestation sac in predicting abortion and stillbirth were higher than that of the area ratio of SCH to gestation sac. CONCLUSION: The volume ratio of SCH to gestation sac by three-dimensional ultrasound in first-trimester plays an important role to predict pregnancy outcome. KEY WORDS: Ultrasonography, Hematoma, Pregnancy outcome, Threatened abortion, ROC curve.

BACKGROUND: It is challenging to predict the outcome of the pregnancy when fetal heart activity is detected in early pregnancy. However, an accurate prediction is of importance for obstetricians as it helps to provide appropriate consultancy and determine the frequency of ultrasound examinations. The purpose of this study was to investigate the role of the convolutional neural network (CNN) in the prediction of spontaneous miscarriage risk through the analysis of early ultrasound gestational sac images. METHODS: A total of 2196 ultrasound images from 1098 women with early singleton pregnancies of gestational age between 6 and 8 weeks were used for training a CNN for the prediction of the miscarriage in the retrospective study. The patients who had positive fetal cardiac activity on their first ultrasound but then experienced a miscarriage were enrolled. The control group was randomly selected in the same database from the fetuses confirmed to be normal during follow-up. Diagnostic performance of the algorithm was validated and tested in two separate test sets of 136 patients with 272 images, respectively. Performance in prediction of the miscarriage was compared between the CNN and the manual measurement of ultrasound characteristics in the prospective study. RESULTS: The accuracy of the predictive model was 80.32% and 78.1% in the retrospective and prospective study, respectively. The area under the receiver operating characteristic curve (AUC) for classification was 0.857 (95% confidence interval [CI], 0.793-0.922) in the retrospective study and 0.885 (95%CI, 0.846-0.925) in the prospective study, respectively. Correspondingly, the predictive power of the CNN was higher compared with manual ultrasound characteristics, for which the AUCs of the crown-rump length combined with fetal heart rate was 0.687 (95%CI, 0.587-0.775). CONCLUSIONS: The CNN model showed high accuracy for predicting miscarriage through the analysis of early pregnancy ultrasound images and achieved better performance than that of manual measurement.

OBJECTIVE: The aim: The aim of the study was to assess the peculiarities of the formation and development of the fetoplacental system, to study the structures of the embryo, gestational sac, chorion in pregnant women with miscarriage. PATIENTS AND METHODS: Materials and methods: A comprehensive ultrasound examination of 50 pregnant women was carried out in the period from 5 to 16 weeks of pregnancy, of which 25 - with a history of miscarriage (main group), and 25 - with an unremarkable medical history (control group). RESULTS: Results: We have identified the following echographic markers of adverse course and outcome of pregnancy in women with miscarriage in embryonic and early fetal periods:- lag of CRL of an embryo by 2 weeks and more at ultrasound examination in terms up to 9 weeks of gestation;- corporal or basal (near the stem of the embryo body) location of chorionic detachment with the formation of retrochorial hematoma with a volume of more than 25 ml;- pronounced progressive decrease in the volume of the gestational sac and amniotic cavity;- pronounced polyhydramnios with the presence of a coarse echopositive suspension in the amnioticcavity. The likelihood of spontaneous miscarriage and the formation of placental dysfunction is higher with the simultaneous detection of 2 or more echographic markers. CONCLUSION: Conclusions: Ultrasound examination is necessary to assess the echographic parameters of the formation and development of the embryo and extraembryonic structures in the first trimester with a history of miscarriage in order to the subsequent choice of rational tactics of pregnancy management.

INTRODUCTION: Routine ultrasound may be used in abortion services to determine gestational age and confirm an intrauterine pregnancy. However, ultrasound adds complexity to care and results may be inconclusive, delaying abortion. We sought to determine the rate of ectopic pregnancy and the utility of routine ultrasound in its detection, in a community abortion service. METHODS: Retrospective case record review of women requesting abortion over a 5-year period (2015-2019) with an outcome of ectopic pregnancy or pregnancy of unknown location (PUL) at a service (Edinburgh, UK) conducting routine ultrasound on all women. Records were searched for symptoms at presentation, development of symptoms during clinical care, significant risk factors and routine ultrasound findings. RESULTS: Only 29/11 381 women (0.25%, 95% CI 0.18%, 0.33%) had an ectopic pregnancy or PUL (tubal=18, caesarean scar=1, heterotopic=1, PUL=9). Eleven (38%) cases had either symptoms at presentation (n=8) and/or significant risk factors for ectopic pregnancy (n=4). A further 12 women developed symptoms during their clinical care. Of the remaining six, three were PUL treated with methotrexate and three were ectopic (salpingectomy=2, methotrexate=1). In three cases, the baseline ultrasound indicated a probable early intrauterine pregnancy. CONCLUSIONS: Ectopic pregnancies are uncommon among women presenting for abortion. The value of routine ultrasound in excluding ectopic pregnancy in symptom-free women without significant risk factors is questionable as it may aid detection of some cases but may provide false reassurance that a pregnancy is intrauterine.

BACKGROUND: Endometrial thickness (ET) has previously been shown to positively correlate with implantation and clinical pregnancy rates. Pregnancies achieved using in-vitro fertilization (IVF) technique are prone to higher rates of early miscarriage. The aim of this study was to compare the effects of expectant management, medical treatment (Misoprostol) and dilation and curettage (D&C) for early miscarriage following IVF cycles on the subsequent cycle outcomes - endometrial thickness and reproductive outcomes. METHODS: A retrospective cohort study of women who underwent embryo transfer, conceived and had first trimester miscarriage with at least one subsequent embryo transfer. ET measurements during fresh or frozen-thawed IVF cycles were assessed for each patient. Comparisons of ET differences between the miscarriage and the subsequent cycles, as well as reproductive outcomes, were performed according to the initial miscarriage management approach. RESULTS: A total of 223 women were included in the study. Seventy-eight women were managed conservatively, 61 were treated with Misoprostol and 84 women underwent D&C. Management by D&C, compared to conservative management and Misoprostol treatment was associated with higher prevalence of a significant (> 2 mm) ET decrease (29.8%% vs. 14.1and 6.6%, respectively; p < .001) and was the only approach associated with a significant increase in the rates of ET under 7 and 8 mm in the following cycle (p = 0.006 and 0.035; respectively). Clinical pregnancy rates were significantly lower following D&C compared with conservative management and Misoprostol (16.7% vs. 38.5 and 27.9%, respectively; p = 0.008) as well as implantation rate (11.1% vs. 30.5.% and 17.7, respectively; p < 0.001). CONCLUSION: Our data suggest that D&C management of a miscarriage is associated with decreased ET and higher rates of thin endometrium in the subsequent IVF cycle, compared with conservative management and Misoprostol treatment. In addition, implantation and pregnancy rates were significantly lower after D&C.

OBJECTIVE: To compare the performance of kisspeptin and beta human chorionic gonadotropin (ßhCG), both alone and in combination, as biomarkers for miscarriage throughout the first trimester. DESIGN: Prospective, nested case-control study. SETTING: Tertiary Centre, Queen Charlotte Hospital, London, United Kingdom. PATIENT(S): Adult women who had miscarriages (n = 95, 173 samples) and women with healthy pregnancies (n = 265, 557 samples). INTERVENTION(S): The participants underwent serial ultrasound scans and blood sampling for measurement of plasma kisspeptin and ßhCG levels during the first trimester. MAIN OUTCOME MEASURE(S): The ability of plasma kisspeptin and ßhCG levels to distinguish pregnancies complicated by miscarriage from healthy pregnancies unaffected by miscarriage. RESULT(S): Gestation-adjusted levels of circulating kisspeptin and ßhCG were lower in samples from women with miscarriages than in women with healthy pregnancies by 79% and 70%, respectively. The area under the receiver-operating characteristic curve for identifying miscarriage during the first trimester was 0.874 (95% confidence interval [CI] 0.844-0.904) for kisspeptin, 0.859 (95% CI 0.820-0.899) for ßhCG, and 0.916 (95% CI 0.886-0.946) for the sum of the two markers. The performance of kisspeptin in identifying miscarriage improved with increasing length of gestation, whereas that of ßhCG worsened. A decision matrix incorporating kisspeptin, ßhCG, and gestational age had 83% to 87% accuracy for the prediction of miscarriage. CONCLUSION(S): Plasma kisspeptin is a promising biomarker for miscarriage and provides additional value to ßhCG alone, especially during later gestational weeks of the first trimester.

Currently, ultrasound (US) is a valuable imaging tool for the initial assessment and evaluation of the female genital organs, uterus, and adnexa. However, it is easy to overlook the uterine cervix while conducting a pelvic US. Uterine cervical lesions may range from benign to malignant in nature. Therefore, meticulous examination with US may play a key role in assessing uterine cervical lesions. Although there is substantial overlap in the US findings across various uterine cervical lesions, some US features, in tandem with clinical characteristics, may suggest a specific diagnosis. Familiarity with the clinical settings and US characteristics of different uterine cervical lesions can support prompt and accurate diagnosis of suspicious lesions. This review article aims to describe the features of US and possible values for distinction of these lesions in the uterine cervix.

PURPOSE: Standard treatment for retained products of conception (RPOC) is dilation and curettage (D&C), however, this brings a risk of intrauterine synechiae and subsequent fertility issues. A treatment strategy to avoid D&C is medical management with misoprostol. The justification for misoprostol in this setting is extrapolated from miscarriage and termination literature, however, no studies have looked specifically in the setting of RPOC. The purpose of this study is to determine the efficacy of misoprostol as definitive management of RPOC. MATERIALS AND METHODS: A retrospective cohort study was conducted from January 2016 to March 2017 at an Early Pregnancy Assessment Clinic. Patients diagnosed with RPOC with clinical symptoms and ultrasound findings of endometrial mass and/or doppler flow treated expectantly, medically with vaginal misoprostol or with a suction D&C underwent a chart review. Primary outcome was resolution of RPOC without surgical intervention. RESULTS AND CONCLUSIONS: Of 1743 unique pregnancies, 189 women were diagnosed with RPOC. 34% (65/178) chose misoprostol for management of RPOC. Baseline demographics between the three treatment modalities (expectant, medical, surgical) were comparable. 65% (42/65) of patients who took misoprostol avoided D&C. Misoprostol is most effective (76%) in the setting of RPOC if the primary treatment for miscarriage was expectant management, with less success with primary medical management (44%) and primary surgical management (40%).

OBJECTIVE: To demonstrate a simple, stepwise strategy for robot-assisted abdominal cerclage placement before pregnancy. DESIGN: Demonstrative video presentation. Surgical footage surrounding a case report is used to describe a four-step technique for robot-assisted abdominal cerclage placement in women with recurrent pregnancy loss or other anatomic variants before pregnancy. This video article was reviewed by the Investigational Review Board and further investigation was waived because the study was "not considered human subject research." SETTING: Tertiary medical center. PATIENT(S): A 38-year-old G4P0220 (Gestations: 4, Term deliveries: 0, Preterm deliveries: 2, Abortions: 2, Living children: 0) with a history of two second trimester losses who had failed a prior history-indicated transvaginal cerclage (Fig. 1). INTERVENTION(S): The patient underwent an uncomplicated robot-assisted abdominal cerclage using a four-step strategy: Step 1, create the bladder flap; Step 2, identify pertinent anatomy; Step 3, place the cerclage; and Step 4, hysteroscopy. MAIN OUTCOME MEASURE(S): Intraoperative technique presenting a four-step method to ensure successful robot-assisted abdominal cerclage placement. RESULT(S): Robot-assisted abdominal cerclage is a safe, viable alternative to traditional abdominal cerclage placed via laparotomy. This video outlines four critical steps to facilitate placement and decrease patient morbidity. This patient did well operatively without increased blood loss or operative time and was discharged home on postoperative day 1. She went on to have a successful future pregnancy and currently is scheduled for an elective cesarean section at term. CONCLUSION(S): Abdominal cerclages significantly improve pregnancy and neonatal outcomes in women who previously have failed transvaginal cerclage. Robot-assisted abdominal cerclage placement allows a minimally invasive approach with enhanced dexterity and better visualization for the surgeon compared with conventional laparoscopy or laparotomy, as well as decreased pain and shorter recovery time for patients. This video demonstrates placement of a robot-assisted abdominal cerclage in a patient with recurrent pregnancy loss using a simple four-step strategy to ensure successful, correct, and easy placement. To our knowledge, this is the first video demonstrating a stepwise approach to robot-assisted abdominal cerclage placement.

We evaluated the accuracy of the ultrasound signs suggestive of complete hydatidiform mole (CHM) and partial hydatidiform mole (PHM) in a cohort of women with histologically confirmed hydatidiform mole (HM) who presented with early pregnancy failure, including 103 CHM and 95 PHM for which ultrasound images were available. The accuracy of the differential diagnosis was significantly (p < 0.001) greater during secondary examination of ultrasound images compared with the original primary ultrasound examination. The interobserver agreement analysis indicated only a fair to moderate agreement between the two examinations (kappa value 0.41; 95% CI 0.29-0.53). Most HM present as early pregnancy failure and identification of early ultrasound signs can improve the differential diagnosis between CHM and PHM.

Background: Point-of-care ultrasound (POCUS) implemented through task shifting to nontraditional users has potential as a diagnostic adjuvant to enhance acute obstetrical care in resource-constrained environments with limited access to physician providers. Objective: This study evaluated acute obstetrical needs and the potential role for POCUS programming in the North East region of Haiti. Methods: Data was collected on all women presenting to the obstetrical departments of two Ministry of Public Health and Population (MSPP)-affiliated public hospitals in the North East region of Haiti: Fort Liberté Hospital and Centre Medicosocial de Ouanaminthe. Data was obtained via retrospective review of hospital records from January 1 through March 31, 2016. Trained personnel gathered data on demographics, obstetrical history, diagnoses, clinical care and outcomes using a standardized tool. Diagnoses a priori, defined as those diagnoses whose detection could be assisted with POCUS, included multi-gestations, non-vertex presentation, cephalopelvic disproportion, placental abruption, placenta previa, spontaneous abortions, retained products and ectopic pregnancy. Results: Data were collected from 589 patients during the study period. Median maternal age was 26 years and median gestational age was 38 weeks. The most common reason for seeking care was pelvic pain (85.2%). Sixty-seven (11.5%) women were transferred to other facilities for higher-level care. Among cases not transferred, post-partum hemorrhage, infant mortality and maternal mortality occurred in 2.4%, 3.0% and 0.6% of cases, respectively. There were 69 cases with diagnoses that could have benefited from POCUS use. Between sites, significantly more cases had the potential for improved diagnostics with POCUS at Fort Liberté Hospital (19.8%) than Centre Medicosocial de Ouanaminthe (8.2%) (p < 0.001). Conclusion: Acute obstetrical care is common and POCUS has the potential to impact the care of obstetrical patients in the North East region of Haiti. Future programs evaluating the feasibility of task shifting and the sustainable impacts of acute obstetric POCUS in Haiti will be important.

OBJECTIVES: (1) To study the predictors of pregnancy continuation up to 28 weeks in first-trimester threatened miscarriage after a single clinical and ultrasound (US) evaluation. (2) To assess the role of both clinical and US predictors in counseling and decreasing repeated emergency follow-up scans. METHODS: A prospective observational study that included a cohort of 241 patients with threatened miscarriage (≥6-12 weeks) was conducted. They had a single clinical and US evaluation, and then they were contacted by weekly phone calls until completing 28 weeks' gestation or reporting miscarriage. Independently, all patients were followed by the recommended routine US scanning with or without emergency visits. RESULTS: Two hundred thirty-three patients completed the study, of whom 193 patients continued up to 28 weeks' gestation, and 40 miscarried (17.1%). Only spotting/mild bleeding episodes and progesterone treatment were the clinical predictors of fetal viability. The embryonic/fetal heart rate (E/FHR) was the best single US predictor, with a specificity and positive predictive value of 95.3% and 97.2%, respectively. Combining 3 US parameters, at their best cutoff points (E/FHR >113 beats per minute, crown-rump length >19.9 mm, and gestational sac diameter >27.3 mm), had a specificity and positive predictive value of 98% and 99% (first-trimester US triad of fetal viability). CONCLUSIONS: [1] In first-trimester threatened miscarriage, clinical parameters that could predict fetal viability included spotting/ mild bleeding and progesterone treatment. [2] After a single US scan, the presence of at least an E/FHR of greater than 113 bpm or the suggested first-trimester US triad appeared as a simple, measurable, and effective predictor of pregnancy continuation up to 28 weeks. [3] These US predictors are not to replace the recommended scheduled scanning during pregnancy. [4] This can improve patients' counseling and decrease the need for repeated emergency follow-up scans. Otherwise, there is an indication for repeating US scans at a 1-week to 10-day interval.

INTRODUCTION: A scoring system combining clinical history and simple ultrasound parameters was developed to predict early pregnancy viability beyond the first trimester. The scoring system has not yet been externally validated. This study aimed to externally validate this scoring system to predict ongoing pregnancy viability beyond the first trimester. METHODS: This prospective observational cohort study enrolled women with singleton intrauterine pregnancies before 12 weeks of gestation. Women underwent examination and ultrasound scan to assess gestational sac size, yolk sac size, and fetal pulsation status. A pregnancy-specific viability score was derived in accordance with the Bottomley score. Pregnancy outcomes at 13 to 16 weeks were documented. Receiver-operating characteristic curve analysis was used to assess the discriminatory performance of the scoring system. RESULTS: In total, 1508 women were enrolled; 1271 were eligible for analysis. After adjustment for covariates, miscarriage (13%) was significantly associated with age ≥35 years (odds ratio [OR]=1.99, 95% confidence interval [CI]: 1.19-3.34), higher bleeding score (OR=2.34, 95% CI: 1.25-4.38), gestational age (OR=1.17, 95% CI: 1.13-1.22), absence of yolk sac (OR=4.73, 95% CI: 2.11-10.62), absence of fetal heart pulsation (OR=3.57, 95% CI: 1.87-6.84), mean yolk sac size (OR=1.25, 95% CI: 1.06-1.47), and fetal size (OR=0.82, 95% CI: 0.77-0.88). The area under the receiver operating characteristic curve was 0.91 (95% CI: 0.89-0.93). Viability score of ≥1 corresponded to a >90% probability of viable pregnancy. CONCLUSIONS: The scoring system was easy to use. A score of ≥1 could be used to counsel women who have a high likelihood of viable pregnancy beyond the first trimester.
